On 29 March 2015, fighting broke out between the Arakan Army’s (AA) Tactical Unit No. 5 and Myanmar Army Infantry Battalion No. 289 in one of the first major attacks for the AA outside of Kachin State where they are largely based. The attack, on the ethnic Chin village of Pyin So, Paletwa Township, Chin State, forced hundreds of villagers to flee. According to one villager, speaking to the Chin Human Rights Organisation, the fighting had occurred because Government soldiers stationed in the village had captured an Arakan Army soldier, three days before the clash.
